debugging dll files in a .NET project

I have a .NET project which contains a dll which I have created myself. Now, there is some problem, either in my calling code, or in the dll, but I can't figure out what it is because I can't debug the dll for some reason.

Now, I don't know why, but I have added that dll to other projects, and when an error occurs, the debugger opens up the dll and automatically debugs it. In this project, however, for some reason it just says 'there is no source code for this location' or something to that effect and the dll can't be opened or debugged (or at least, I'm not sure how to do it if it doesn't happen automatically). If I alter something in the dll outside of the project, the project that can debug the dll even tells you something has changed and asks if you want to load the changes into the dll that is part of the project.

well i don't remember if i did it any different way the first time. But usually i just right click on the project and select 'add reference' and the browse to where my dll is and then add it... so i guess i'm just referencing the dll.

or is there a chance i'm doing something else also in the other projects? how can i tell, if that's the case.

Yeap thanks Carl... that was it. Didn't think about that. Think I used the release version because the debug version didn't update when I built the project. So, I just tried to run the project and there was an error because you can't run a dll but it still built the debug version anyway and so i replaced with that.

Wouldn’t it be nice if you could test whether an element is contained in an array by using a Contains method just like the one available on List objects? Wouldn’t it be good if you could write code like this?
